Vocabulary construction counts repeated labels as separate classes · case 02
Vocabulary construction counts repeated labels as separate classes.
Case contract
Return [vocabulary,indices], where vocabulary lists distinct labels in first-seen order and indices encode input labels.
Why this case matters
A small deterministic training-data operation makes label ownership and ordering explicit.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| repeat shares index | [["b", "a", "b"], [0, 1, 2]] | [["b", "a"], [0, 1, 0]] | Failed |
